I apologize to anyone that has received and invite from me to join feedspot (a kind of RSS reader service). My gmail contact list was somehow accessed without my consent. They did seem legit, collecting and aggregating RSS feeds and making it easy to share on social media, running contests and on-line exhibitions BUT they have ruined their reputation unrecoverable by using email my contacts without consulting me.
PLEASE IGNORE ANY FEEDSPOT INVITES
Feedly is a much better service, I can recomend if you like using an RSS reader
